Hi Yuki,
You have some valid points, Though you sound more like your running a
system for graphic arts & Modeling. ;-)
But to take things into context, I was infering weekly backups for the cd.
Yes, I'd agree that Daily backups would be a pain.
There is one fundamental I can see that seperates many of our views - And it's
probably just enforced habbit on my behalf!
And it is that I - As a rule of thumb - NEVER powerdown any of my drives.
There are various reasons at to why - Suffice to say - That my drives
generaly just keep on goin on.....
As to lightning strikes - Yup I've had a couple of those - One Blew my
Cable modem - Another just took out the light fuses - and before that, The
Video player
was fried.
Needless to say - I run UPS's & Protected PowerBoards (Not just surge
arresters in these things - Heck they are mounted in solid Aluminium Bar)
Also, Perhaps because I only use EOD - Daily backups are a bit much for me.
I'll generaly Zip up my ASX database every 3 or so days.
Then Backup the lot to the fileserver every month or so - Depending on how much
work I do. Special Items of interest generaly get backed up straight away.
BTW - The fileserver is not windows based.
Anyway - IMHO - After Zipping your data up - Weekly backups to CD is still
a valid option for many non super computer users out there ;-)
